1SHORT DESCRIPTION
2
3This Perl module provides routines for checking validity of email
4address.
5
6It makes several checks:
7
81) it checks the syntax of an email address;
9
102) it checks if there any MX records or A records for the
11 domain part of the email address;
12
133) it tries to connect to an email server directly via SMTP to check
14 if mailbox is valid. Old versions of this module performed this
15 check via the VRFY command. Now the module uses another check; it
16 uses a combination of MAIL and RCPT commands which simulates
17 sending an email. It can detect bad mailboxes in many cases.
18
19This module was designed with CGIs (or any other dynamic Web content
20programmed with Perl) in mind. Usually it is required to quickly check
21e-mail addresses in forms. If the check can't be finished in
22reasonable time, the e-mail address should be treated as valid.
